  1. Basic Plant Structure

  2. Happy Monday!Bellwork: February 17Copy the 2 sentences and underline key words The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these most likely increases? • Natural selection • Genetic variation • Environmental fitness • Reproductive mutations

  3. CO: I will describe the interactions between systems in plants. I will describe the reproductive parts of a plant.LO: I will write notes. I will discuss plants with a partner. I will read about plant reproductive organs.

  4. Science Fact of the Day:Fingernails grow four times as fast as toenails.

  5. Anticipation Guide:Decide if the following statements are true or false with your partner • Some plants are single celled organisms • Plants are prokaryotic and animals are eukaryotic • Plants are photosynthetic autotrophs • Plants have chitin in their cell walls • Pollination is a part of plant reproduction • There are carnivorous plants

  6. Plants What makes a plant a plant? Plants are eukaryotic Plants have cell walls made of cellulose Plants make their own energy through photosynthesis Plants are multicellular

  7. What plants need to survive… 1. Sunlight 2. Water 3. CO2 & Oxygen 4. Nutrient and water movement

  8. Plant Parts/Systems • Reproductive System = Flower (with male and female parts) • Transport System = tissues in stem • Nutrient System = Leaf + Root • Structural Support System = Stem + Roots All of these parts and systems work together to help a plant maintain homeostasis.

  9. Think-Pair-ShareHow do the leaves, stem, and roots work together to help a plant maintain homeostasis?

  10. Is It a Stem, Leaf, Root, Flower, Fruit or Seed?

  11. Plant Reproductive Structure • Tomorrow you will be dissecting a flower, identifying the parts, and discussing how plants interact with their environment. • So let’s take a few minutes to talk about the structure of flowers…

  12. Flower Parts Complete flowers have four parts. • Stamen – male part, include anther and filament • Anther: produces pollen • Pollen: plant “sperm”, fertilizes eggs Carpel (pistil) –female part, includes stigma, style and ovary - Ovary: organ that holds egg, where fertilization occurs Sepals– protection for flower during development Petals– protection for flower as well as attracting pollinators

  13. Today’s assignment • Read the article on plant structure and reproduction. Highlight or underline the key words. • Complete the questions. • Color the flower according to the directions. • Label each flower part (ex. A=anther) • This is a grade due at the end of class.

  14. Bellwork: February 18Label the parts of the flower. 7 4 1 2 6 5 3
